Interest in Sr\(_{2}\) IrO\(_{4}\)  compound were driven initially due to its structural analogue with high Tc cuprate based superconductor from the structural, magnetic and electronic point of view.[1]}, [2]}, [3]} Many theoretical studies predicted a possibility of superconductivity upon electron or hole doping in Sr\(_{2}\) IrO\(_{4}\) .[4]}, [5]}, [6]} In contradiction to these results, the transport and magnetic measurements on the doped bulk samples did not show superconductivity. In this compound, electron doping can be achieved by substituting La in the place of Sr ion or by introducing oxygen vacancies.[7]}, [8]}, [9]}, [10]} The hole doping is realized by substituting Ru/Rh at Ir site or K at Sr site.[11]}, [12]}, [13]}, [14]} It has been observed that even a small amount of chemical doping led to the evolution of spin-orbit Mott insulating state into an exotic metallic state with the increase in the doping level. On the other hand, oxygen deficient single crystals produced by annealing in vacuum exhibited a metal to insulator transition at low temperatures.[15]} The nature of the metallic state induced by these electron or hole doping is a subject of interest in recent years due to their novel properties such as robust AFM metallic state,[16]} phase separation[7]}, [12]} etc,.
